Item Activity Fulfilled/Complete
22 Option L59
EMERGENCY
STOP category 1,
230 V AC
EMERGENCY STOP category 1 stops the drive in a controlled
manner. No additional wiring is necessary when implemented in
conjunction with option L45.
If the cabinet unit is integrated in an external safety circuit, however,
the contact must be looped in via terminal block -X120. The timer
relay -K121 must be adapted to match system requirements (see
"Electrical installation / EMERGENCY STOP category 1, 230 V AC
(option L59)").
23 Option L60
EMERGENCY
STOP category 1,
24 V AC
EMERGENCY STOP category 1 stops the drive in a controlled
manner. No additional wiring is necessary when implemented in
conjunction with option L45.
If the cabinet unit is integrated in an external safety circuit, however,
the contact must be looped in via terminal block -X120. The timer
relay at -K120 must be adapted to match system requirements (see
"Electrical installation / Other connections / EMERGENCY STOP
category 1, 24 V AC (option L60)").
24 Option
L61/L62/L64/L65
25 kW/125 kW
50 kW/250 kW
braking unit
The connecting cables and ground for the braking resistor must be
connected to terminal block –X5: 1/2. A connection must be
established between the braking resistor thermostatic switch and
customer terminal block –A60. When commissioning via AOP30, the
settings for evaluating "external fault 3" must be made. The settings
for evaluating the thermostatic switch as "external fault 2" must be
made (see "Electrical installation / Other connections / Braking unit
25 kW / 125 kW (option L61 / L64); braking unit 50 kW / 250 kW
(option L62 / L65)").
25 Option L83
Thermistor motor
protection device
(alarm)
The PTC thermistor sensors (PTC resistor type A) must be connected
to the thermistor motor protection unit -F127 at terminals T1 and T2
for alarms (see "Electrical installation / Other connections /
Thermistor motor protection device (option L83/L84)").
26 Option L84
Thermistor motor
protection device
(shutdown)
The PTC thermistor sensors (PTC resistor type A) must be connected
to the thermistor motor protection unit -F125 at terminals T1 and T2
for shutdown (see "Electrical installation / Other connections /
Thermistor motor protection device (option L83/L84)").
27 Option L86
PT100 evaluation
unit
The resistor thermometers must be connected to evaluation
unit -B140 for the PT100 evaluation. A two-wire or three-wire system
can be used here to connect the PT100 sensors. The sensors are
divided into two groups (see "Electrical installation / Other
connections / PT100 evaluation unit (option L86)"). This must be
taken into account for the evaluation (factory setting).
28 Option L87
Insulation
monitoring
The insulation monitor can only be operated from an insulated
network. Only one insulation monitor can be used in an electrically-
connected network. For line-side control, the signaling relays must be
connected accordingly or, with individual drives (the cabinet unit is
fed via a converter transformer assigned to the cabinet unit),
integrated in the cabinet unit alarm train (see "Electrical installation /
Other connections / Insulation monitoring (option L87)").
Point 7 must also be taken into account:
"Before the cabinet is operated from an ungrounded supply/IT
system, the connection bracket for the basic interference suppression
device must be removed (see "Electrical installation / Removing the
connection bracket for the interference suppression capacitor with
operation from an ungrounded supply")".
